[ros-dev] GCC 4.4

These warnings do not mean overwriting, simply passing a string
constant to a function which takes char *; a potential, not
necessarily a real error. It is allowed in C, not in C++.

Of course, it would be good to check all warnings, some can be bugs.
Not all useful warnings are included in -Wall. It may be worth to
activate more.

But warnings should not deter from adoption of GCC 4.4.

It is not needed in user-mode, too. Nested functions are only used by
PSEH2, and it works well without __enable_execute_stack()
